| | | | | | | | | | | | | Fix the failures in the PPC JIT by marking relocation entries for external symbols (e.g. 'fmod') as needing a stub. This regression was introduced by Evan's jit patch here: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20071231/056749.html With this fixed, the two ExecutionEngine failures are passing on ppc, and the ppc jit works on freebench and olden. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_22@46225 91177308-0d34-0410-b5e6-96231b3b80d8

* Fixes a nasty dag combiner bug that causes a bunch of tests to fail at -O0.Evan Cheng2008-01-162-6/+74
| | | | | | | | | | | | | | | | | | | | | It's not safe to use the two value CombineTo variant to combine away a dead load. e.g. v1, chain2 = load chain1, loc v2, chain3 = load chain2, loc v3 = add v2, c Now we replace use of v1 with undef, use of chain2 with chain1. ReplaceAllUsesWith() will iterate through uses of the first load and update operands: v1, chain2 = load chain1, loc v2, chain3 = load chain1, loc v3 = add v2, c Now the second load is the same as the first load, SelectionDAG cse will ensure the use of second load is replaced with the first load. v1, chain2 = load chain1, loc v3 = add v1, c Then v1 is replaced with undef and bad things happen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46099 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | make the 'fp return in ST(0)' optimization smart enough to look through token factor nodes. THis allows us to compile testcases like CodeGen/X86/fp-stack-retcopy.ll into: _carg: subl $12, %esp call L_foo$stub fstpl (%esp) fldl (%esp) addl $12, %esp ret instead of: _carg: subl $28, %esp call L_foo$stub fstpl 16(%esp) movsd 16(%esp), %xmm0 movsd %xmm0, 8(%esp) fldl 8(%esp) addl $28, %esp ret Still not optimal, but much better and this is a trivial patch.
